Show 344 MR. w. L. SCLATER O N SPECIMENS O F [May 3, Described from a single specimen in the Indian Museum, procured by the late Dr. Jerdon in the Khasia hills in Assam. 5. RANA HASCHEANA, Stoliczka, Journ. As. Soc. Beng. xxxix. 1870, p. 147, pi. ix. fig. 3. A n examination of the type of this species preserved in the Indian Museum shows that it is nearly allied to R. dorice, Boulg. The general shape is the same, the legs are about the same length, and the vomerine teeth commence on a level with the hinder edge of the choanae. The only real distinction is in the toes, which in R. dorice are webbed to the tips, but in R. hascheana for only about one-third of their length. 6. RANA LIMBORGI, sp. n. (Plate XXIV. figs. 3, 3 a.) Vomerine teeth in two oblique groups, commencing on a level with the choanae and extending well behind them ; slight traces of the bony prominences of the lower jaw; head moderate ; snout short, hardly longer than the diameter of the orbit; canthus rostralis very rounded, hardly marked; loreal region almost flat; nostril about equidistant from the tip of the snout and the front of the orbit; interorbital space as broad as the upper eyelid; tympanum distinct, nearly as large as the eye, with a very thick fold above it ; first finger extending slightly beyond the second; toes moderate, slender, only about a third webbed, the web extending only about halfway up the first joint of the digits ; a slight cutaneous ridge along the fifth toe ; tips of fingers and toes but very slightly swollen; subarticular tubercles fairly well developed ; no outer metatarsal tubercle ; a large, compressed, fairly sharp-ridged inner metatarsal tubercle, very nearly as large as the inner toe; traces of a tarsal fold present; the tibio-tarsal articulation reaches the nostril; skin above granular, with slight traces of a granular lateral fold running back on either side from behind the eye and a transverse fold between its posterior borders ; below smooth. Colour above a faded olive-brown, below lighter. Length from snout to vent 24 millim. This species is somewhat intermediate between R. dorice and R. rufescens; from the former it differs in having only very slightly webbed toes and a compressed flattened metatarsal tubercle, and from the latter in its vomerine teeth, which commence cnly on a level with the posterior corners of the choanae, and from both in the presence of its rudimentary glandular lateral fold. This description is taken from a single specimen procured in Tenasserim by M r . Limborg, to w h o m I have dedicated the species. 7. RANA TIGRINA, Daud.; Boulenger, Ind. Rept. p. 449. A small Frog from Penang, described by Stoliczka (Journ. As. Soc. Beng. xxxix. 1870, p. 142) as R. gracilis, var. pulla, seems to be merely the young of R. tigrina; that the type has only just lost the larval tail is shown by the persistence of the tail-scar. |
